Can sent only one packet per connection interval in nrf52832 SDK14.2

[NIDHIN K]

I need maximum throughput in nrf52832. So i enabled DLE and using s132_nrf52_5.0.0_softdevice. The data packet length is 96 bytes in single packet. Conn interval 7.5 and 10ms. Im sending data using 1ms timer isr So data will sent continuously within each 1ms gap, firsr packet is sent successfully and the next packet will send after 20ms because it always return the error  NRF_ERROR_RESOURCES . so i understand only one packet is sending in one connection interval . I increased connection interval then also it send only one packet per conn.interval.

How can able to increase number of packet in one connection interval.

Hi,

Could you tell more about the peer device  ? The peer need to support DLE and support multiple packets per connection interval. 

If you can capture a sniffer trace, it will be easier to analysis and check why it can only send 1 packet per connection interval. 

We need to have a look at the configuration of Max MTU and the event length configuration as well. 

Have you tried to test with the ble_app_att_mtu_throughput example ?
